Supercharger question

Alright guys I really want to KB 2.1L on my 03 gt. I just need to know if I need to get forged intervals and cams or if I should be ok with out them? Also should I get inter cooled or non inter cooled

Depends on your goals.
400 is "okay" on stock internals, but pushing it.
Intercooled is always better.
I'd do 8 psi intercooled and be happy. If I wanted more than 400 (which I do), I'd get a cobra with forged internals and save the money I would have spent on building a 2v.

Intercooled is safer. Depends what psi you choose as whether or not to forged. Up to about 10 i say no above that will be above 450hp and you'll start burning her up

It would be cheaper now to just sc the 2v. Getting a Termi you would have be buying a whole new car, and depending on what you find you either find one close to stock with maybe just pullied and exhaust. Or you might find one that's already built.

That's what I figure that the termi would be the way to go

Eh, I say build the 2v dude. Woot Woot for the 03 04 Cobras but people under estimate the potential of the 2v. I say build it and have something you've built and not just bought.

Between 400 - 450 seems to be the magic number for non forged Mustangs.

Its whatever you want to do. Termi's are getting harder to find and are often abused because of the power people know it has

+100 on the unmolested terminator problem. I've been looking for the unicorn (a factory terminator) for a year now with no results except a handful of wrapper cars that I REALLY don't feel like dealing with. Hoses, lines, and fluids that have sat for 10 years isn't my ideal car to purchase.
The 2v has potential if you dump a fortune into it. Forging everything will be a few thousand plus 4-5k for a used KB 2.2 or small Whipple, then you need the fuel system upgrades, completely redo the suspension, get better tires (and probably wider wheels since very few people have a 10 or 10.5 wide), pay for labor costs, built/replace the transmission so you don't obliterate the poor TR3650s gears and shafts, new clutch, new flywheel,
That's the MINIMUM I would do to have a reliable AND fast car.

You don't have to dump a fortune into a 2v. Just be realistic with your goals. Do you want a 400 - 500hp fun street car or a 1000hp + 40k + dragster.

03 04 Cobras are pretty awesome cars but they are not the best or fastest cars on the street and the solution to every supercharger question is not "sell your car and buy a termi".

Every Cobra I looked at was a piece of shot compared to my car so I kept mine and modified it.

Couldn't be happier with the results.

Build your own... more fun and way greater satisfaction... and I have way less money in my car compared to buying a Cobra.

Plus I won best of show last week on my first show with the car.

As someone who has both they are completely different animals. Fit and finish on my cobra seems of higher quality than my gt and the car feels much different driving with the same size wheels and tires.

Do what you want but the cobras are only going up in value from this point forward. There are still plenty of nice cars out there you just have to know what to look for. There are a good amount of cobra owners like myself who have it as strictly a nice weather playtoy. I had mine for sale a few years back when buying a house but the market for low mileage garage queens wasn't what it is now.

I've had three friends buy low mileage stock cars for high teens in the last two years. They do exist

Bro your car is so sexy! Can you tell me all the parts you had to use to get it to be able to do 450hsp and not kill the engine

Ok so if I get all that stuff it would be safe enough to run 10psi with a good tune and not blow my engine with stock internals

As long as you take care of maintenance and don't rag on it every chance you get you should be alright depending the condition of your motor now

It will be a ticking timebomb to be honest. People claim fi is safe but it always shortens the life of a motor not built for it. I recommend against forced induction on a stock motor if you don't have funds or plans for a new motor in the future.

Every car is different, the best thing you can do is run low boost on a safe tune and pray. There are no guarantees.

I know people will disagree with my post but the facts need to be known. There is no such thing as safw forced induction.

if you cant afford to build it if it blows up then dont boost the GT as its a risk~ and it sucks when it happens if it happens.

For the investment (well its not an investment kiss most of that cash goodbye) on the blower/install you will end up with a car thats maxed out at 400-450rwhp without building the motor and its hard to get huge numbers out of 2v's.

Plus its simply not worth the HUGE risks of getting the motor build (search for the thousands of threads of shops that scew over owners in terms of costing double what it should or more (way more many times) or taking 10 times longer (if ever). Its not worth the huge hassle and BS to get the job done

Thats why I got my 03 cobra, put a pulley and bolt ons, tuned it and BAM done with 450rwhp and its got tons of room to grow if I ever wanted to.

Thanks Midnight, learned a lot on this forum and I had a thread on almost everything... once I figured out what I wanted to do folks here showed how and what to do. This is one of the best Mustang forums.

Rm360 gets credit...I pretty much followed his mods but added a few tweeks of my own.
